Three apparent strangers wowed passers-by with an ‘impromptu’ jam session outside a supermarket in Dallas, Texas.

Jaime Tatos Maldonado was left stunned after seeing a busker joined by two musicians for a seemingly spontaneous jam.

He filmed the clip and uploaded it to his Facebook page, writing: ‘I was walking to kroger and saw this guy playing a song. It sounded good so I decided to record it. By the end of the song three guys started jamming. This truly is music in its simplest form. It really reminds of the Austin days. Enjoy.’

While the performance might not have been entirely spontaneous – the ‘busker’ is Texan musician Jesse Rya – the video is still a lot of fun.
